Description

The present invention relates to a head portion of the tubular container having a positioning protrusion that functions to position along the circumferential direction of the container.

  Conventionally, as a tube container to which an application function is added, there is one in which an application function part is directly provided on the head part of the tube container, and a desired amount of contents can be obtained by using the flexible flexibility of the main part of the tube container. Discharge to the application function unit, and the discharged content is applied directly to the target location by the application function unit, and it is easy to discharge the desired amount of content. As a container for cosmetics such as lipsticks and disinfectants, it is not necessary to attach it, and it can be used in a simple and hygienic state, and it is easy to carry because it is easy to reduce size and weight. Widely used.

  For this tube container, positioning (position) along the circumferential direction of the tube container is required for printing on the outer surface of the main body for storing the contents, filling and sealing of the contents, and assembly of the main body and the head. However, a conventional technique for positioning the main body and the head is disclosed in Japanese Patent Laid-Open No. 10-307006.

  The above-described prior art prints a positioning mark that emits light when irradiated with ultraviolet rays on the main body, and emits the mark when irradiated with ultraviolet light, and detects this with a sensor to achieve positioning. Because it is possible to make it invisible with visible light, positioning marks stand out as unnecessary marks in the design, and there is a sense of incongruity between the product design, characters, and the printed surface of the design, or positioning of characters and designs Since it must be printed in a place without a mark, it is excellent in solving the inconvenience that printing cannot be performed on a certain range of the main body.

JP-A-10-307006

  Although the above-described conventional technology certainly exhibits excellent operational effects, when a head portion having a directivity and a main body portion are assembled like a head portion with a coating function, printing formation is performed. It is necessary to achieve the assembly of the main body part and the head part by aligning the head part with the positioning mark as a reference, and there is a complaint that the molding process including the printing of the tube container tends to be complicated. It was.

  That is, the tube container including printing in the prior art is formed into a sleeve material 18 (see FIG. 5 (a)) formed in advance in a dimension longer than the sleeve 17 having a predetermined length, as shown in FIG. First, a temporary head mounting process for attaching the temporary head 19 (see FIG. 5B) is performed, and then a printing process (see FIG. 5C) for printing the print display 21 and the positioning mark 22 is performed. A cutting process (see FIG. 5D) is performed to cut off the unnecessary cutting pieces 20 including, from the sleeve material 18 and complete the sleeve 17 with the printed display 21.

  The molded sleeve 17 is assembled in a state of positioning processing (see FIG. 5E) with a positioning mark 22 with respect to a head molding device 23 such as an injection molding device, and this sleeve 17 is used as an insert material for head molding processing (see FIG. 5E). 5E), the tube container 1 in which the main body 2 and the head 3 shown in FIG. 5F are aligned is completed.

  As described above, in the tube container in which the head portion having directionality is attached to the main body portion, the processing steps until the printing / molding completion are many and complicated, so that it takes time and the “provisional head 19”. ”, Which requires a dedicated member that is no longer necessary.

  Therefore, the present invention has been developed to satisfy the above-mentioned demands in the prior art, and it is a technical problem to provide a positioning function portion in a head portion having directionality. It aims to be able to achieve it based on the part.

Among the means for solving the above technical problems, the main configuration of the present invention is as follows.
The head of the tube container,
Erecting the mouthpiece piece on the upper end of the screw cylinder wall to which the cap covering the head part is attached and detached,
Opening a discharge port on the inclined top wall inclined in a certain direction while closing the upper end of the mouthpiece piece, forming a coating function part on the outer surface of the inclined top wall;
Providing positioning protrusions on the upper part of the screw cylinder wall in a configuration that does not hinder the attachment / detachment of the cap
Positioning the positioning protrusion on the side opposite to the inclination direction of the inclined top wall;
It is in.

  A discharge port is established in the inclined top wall of the mouthpiece piece, and the application function part is formed on the outer surface of this inclined top wall, so the contents discharged from the discharge port can be directly applied. Therefore, the discharged contents can be directly applied to the target location by the tube container.

  Since the positioning protrusions are positioned above the screw cylinder wall in a configuration that does not hinder the attachment and detachment of the cap, when the cap is attached to the head part, the entire positioning protrusion is located within the cap. Since it is located above the screw cylinder wall, it is located at the upper end portion of the head portion in the same manner as the mouth tube portion.

Positioning protrusion, since the inclination direction of the inclined top wall was positioned on the opposite side, with respect to coating operation region of the coating function portion formed on the outer surface of the inclined top wall, completely outside the area of the positioning protrusion Can be located.

Another configuration of the present invention, in addition to serving as the main structure described above, to form a diameter-reduced step portion between the screw cylinder wall and the mouth tube piece, the positioning protrusion in the diameter-reduced step portion, It is provided in a configuration that does not protrude laterally from the reduced diameter step portion.

  In the case where the positioning protrusion is provided on the reduced diameter step portion so as not to protrude sideways, the degree of protrusion of the positioning protrusion can be suppressed within the width range of the reduced diameter step portion.

Another configuration of the present invention, in addition to serving as the main structure described above, the outer surface of the inclined top wall, to constitute a coated functional portion and the coated surface is smooth surface, is intended.

  In the case where the outer surface of the inclined top wall is formed of a flexible application body that allows the contents to pass and the application function unit is configured, the impregnation operation of the discharged contents to the application body is utilized, This content can be spread and applied to the target location.

Configuration of the main serving molding and printing methods tube container using a structure of the present invention,
Forming a tube container by performing a head molding process in which a head portion having positioning protrusions is insert-molded into a sleeve molded to a certain length,
After forming the tube container, performing positioning processing along the circumferential direction by the positioning protrusion of the head part,
After performing the positioning process, performing the print processing of the print display on the main body surface of the tube container,
It is in.

  Since the temporary head is not assembled, it is not necessary to provide a cut piece, and the sleeve can be formed to have a certain size from the beginning.

  In the head molding process, the positioning function portion is formed in the head part to be molded, so that it is not necessary to position the sleeve with respect to the head part to be molded.

  Since the printing process after positioning the molded tube container with respect to the main body portion is performed according to the positioning protrusions formed on the head portion, it is not necessary to print a positioning mark on the surface of the main body portion.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the serving main configuration of the present invention, the discharged contents, it is possible to obtain a high convenience that can be applied to the target site by directly tube container, it is possible to obtain a hygienic handling, further Since the discharged contents can be applied immediately to the target location, the effective effect of the contents can be effectively exhibited.

  Since the positioning projection piece is entirely located within the cap, there is no need to increase the diameter of the tube container for the positioning projection piece. Therefore, the positioning projection piece can sufficiently meet the demand for miniaturization and slimming. In addition, since the positioning protrusion is located at the upper end of the head part, it is located in a state where it is easy to monitor from outside and easily contact without intentional interference with other components of the tube container, For this reason, it becomes easy to function as a positioning function part both optically and mechanically.

Since the positioning protrusion is positioned on the side opposite to the inclination direction of the inclined top wall, the positioning protrusion can be positioned completely outside the application operation area, so that the positioning protrusion interferes with the application operation. There is no problem and a good coating operation can be obtained.

  If the positioning protrusion is provided on the reduced diameter step so that it does not protrude laterally from the reduced diameter step, the degree of protrusion of the positioning protrusion can be reduced and the width of the reduced diameter step It can be kept within the range, and since it does not get in the way of releasing from the molding die of the head part on which the positioning protrusions are molded, further downsizing and slimming can be obtained. It is possible to make the tube container suitable for the head, and it is possible to properly perform the injection molding of the head part without difficulty.

  In the case where the outer surface of the inclined top wall is an application surface that is a smooth surface and the application function part is configured, the discharged contents can be applied to the target location with less tactile stimulation. Therefore, the contents can be suitably applied to sensitive parts such as affected parts and soft parts such as lips.

  In the case where the outer surface of the inclined top wall is formed of a flexible application body that allows the contents to pass and the application function part is configured, the contents can be spread and applied to the target location. Good stretch application can be achieved.

In the main serving molding and printing methods tube container using a structure of the present invention, it is possible to reduce the processing step, and speed up the production rate of the tubular container, to obtain a reduction in manufacturing cost In addition, since it is possible to eliminate the occurrence of excised pieces such as a temporary head, it is possible to eliminate the waste of materials and to effectively save resources.

  In the head molding process, it is not necessary to position the sleeve with respect to the head part to be molded, so that the head molding process itself is easy to perform.

  Since there is no need to print a positioning mark on the surface of the main body, the degree of freedom of print display applied to the surface of the main body can be increased, and an effective print display can be obtained accordingly.

  Since the printing process is performed after the head molding process, when the head is molded by injection molding or press molding using the sleeve as an insert material, the thermal effect acting from the molding device or when the sleeve is assembled to the molding device The mechanical influence such as friction generated between the assembly portion and the sleeve is not added to the print display as an adverse effect, and thus the display state of the formed print display is safely maintained. be able to.

These are explanatory drawings which show an example of the conventional shaping | molding process process example.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS.
The head portion 3 (see FIGS. 1 to 3) of the tube container 1 according to the present invention has, as an insert material, the main body portion 2 at the upper end of a flexible cylindrical main body portion 2 which is a main portion for storing contents. It is integrally molded by means such as injection molding or press molding, and is composed of a shoulder wall 4, a screw cylinder wall 5, and a mouthpiece piece 7.

  The shoulder wall 4 is a portion constituting the connection portion of the head portion 3 with the main body portion 2 and has a tapered cylindrical structure that is inclined downwardly outward. In the illustrated embodiment, the entire tube container 1 is It is narrow to make it slim and suitable for carrying.

  The threaded cylinder wall 5 erected on the upper end of the shoulder wall 4 is formed with a thread on the outer peripheral surface to constitute a part with a detachable assembly of the cap 13 that covers the head part 3 and is detachably assembled. In addition, a mouthpiece piece 7 is provided upright at the upper end of the screw cylinder wall 5 via a reduced diameter step portion 6.

  The mouthpiece piece 7 has a top cylindrical shape having an inclined top wall 8, and the inclined top wall 8 forms an outer surface that is inclined downward in a certain direction that is the front direction, and has a discharge port of an appropriate size. 10 is established, and the discharge of the contents to the application function part formed on the outer surface of the inclined top wall 8 is enabled.

  The reduced diameter step portion 6, which is a boundary portion between the screw cylinder wall 5 and the mouthpiece piece 7, is provided with a positioning projection piece 12 formed in a rectangular parallelepiped shape. Is provided on the rear outer surface of the cylindrical wall in a state protruding from the outer surface and not protruding rearward from the reduced diameter step portion 6.

  Thus, since the positioning protrusion 12 is provided on the rear side of the mouthpiece piece 7, it is not located in the application region formed by the inclined top wall 8, that is, the application region formed on the front side. As a result, there is no need to increase the diameter of the head portion 3 because it does not interfere with the application operation of the application function portion and does not protrude rearward from the reduced diameter step portion 6. The positioning protrusion 12 does not become an obstacle to the die-cutting of the molding die for molding the head portion 3, thereby enabling the head portion 3 to be molded smoothly.

  Further, since the positioning projection piece 12 is positioned in a state where the whole is exposed at the upper end portion of the head piece portion 3, that is, the head portion 3, it is easy to detect optically and mechanically. It becomes easy to contact, and it is the structure which is easy to perform positioning operation | movement optically and mechanically by this.

  1 is configured by forming the outer surface of the inclined top wall 8 on a smooth application surface 9, and the application surface from the discharge port 10 is shown. The contents discharged on the sheet 9 are directly applied to the target location using the smoothness of the application surface 9 and the low irritation.

  In addition, the second configuration example of the application function unit shown in the embodiment of FIG. 3 is made of a flexible material that allows the contents to pass through the outer surface of the inclined top wall 8 and impregnates the contents. The application body 11 is positioned, and the contents discharged from the discharge port 10 are applied by rubbing the application body 11 in a state where the application body 11 is impregnated.

  As the application body 11, what is generally used for this kind of application function part can be used, and use of sponge, a nonwoven fabric, etc. is possible.

  A cap 13 (see FIG. 1) that is detachably assembled to the head portion 3 has a top cylindrical shape that covers the head portion 3, and is externally fitted to the screw cylinder wall 5 of the head portion 3 and screwed. In the case of the first embodiment of the application function unit shown in FIG. 1, an inclined top is provided at the center of the lower surface of the top wall 15. A plug piece 16 is provided in a hanging manner for fitting and sealing the discharge port 10 opened in the wall 8.

  Next, an example of the forming method and the printing method of the tube container 1 using the head portion 3 according to the present invention will be described in order with reference to FIG.

  An excision process (see FIG. 4B) is performed in which an extra excision piece 20 is excised from the sleeve material 18 (see FIG. 4A) that has been molded in advance to form a sleeve 17 having a predetermined length. It is to be noted that the excision processing of the excision piece 20 becomes unnecessary by making the cut dimensions coincide with the dimensions of the sleeve 17 from the beginning of the cutting and molding of the sleeve material 18.

  The sleeve 17 cut and molded to a certain length is assembled to the head molding device 23 and subjected to a head molding process (see FIG. 4C), and the tube shown in FIG. The container 1 is formed.

  Once the tube container 1 is formed, the positioning protrusion 12 is used to perform positioning processing of the tube container 1 with respect to the printing device (not shown), and then the printing device performs printing processing (see FIG. 4E). Thus, the forming of the tube container 1 with the print display 21 is completed.

As is apparent from the above description, the tube container forming / printing method using the main configuration of the present invention is substantially composed of three processing operations of a head forming process, a positioning process, and a printing process. The handling process is extremely simple, and the tube container 1 with the print display 21 can be quickly formed.

  Further, as shown in FIG. 4 (e), the tube container 1 with the printed display 21 is not provided with the positioning mark 22, so that the appearance appearance of the tube container 1 may be deteriorated by the positioning mark 22. Since there is no position mark 22 and there is no positioning mark 22, the area where the print display 21 can be given can be enlarged, which facilitates the formation of the desired print display 21.

  And since generation | occurrence | production of the cut piece 20 including the temporary head 19 can be eliminated, the amount of discarded materials can be greatly reduced, and a high resource saving effect can be obtained thereby. It becomes.

  Further, since the positioning protrusion 12 is a projecting structure, any of optical means and mechanical means can be adopted as positioning means using the positioning protrusion 12, and this is easy to implement. Positioning means can be freely adopted.

  Furthermore, since the printing process is performed on the molded tube container 1, the head molding process does not adversely affect the molded print display 21 thermally and mechanically.

Although a rectangular parallelepiped structure example is shown as the positioning projection piece 12, the structure of the positioning projection piece 12 is not specified as a rectangular parallelepiped shape, and it is reduced in a form that can be easily released from the molding die. Any shape may be used as long as it does not protrude outward from the diameter step portion 6.

As described above, the head portion of the tube container according to the present invention is applied not only to the possibility that the positioning means applied to the tube container may deteriorate the appearance of the tube container as a product, but also to the tube container. since it is possible to increase the printing display of the display function, widespread use expand as a head portion of the tube container can be expected.
